In current template in "Main Menu" section we used:

• Main Menu (MegaMenu from template)
• [=] Menu (Off Canvas "Mobile" SideBar Menu, it can be disabled from desktop view via template settings)
• Call Now module (Top1 position) - can be edited in template settings or replaced with custom module

Of course you don't have to use all demo modules (objects).

For example it pretty easily to disable Off Canvas [=] menu from desktop view only.
